>> A new generation of ultra-thin energy-efficient OLED display challenges LCD screen 21th,Mar,2017
A new generation of ultra-thin, energy-efficient display is entering the market. This display can extend the battery life to a new limit (perhaps one day), thus posing a challenge for heavier, power-hungry LCDs.
A new display that glows itself can provide vivid video images for smartphones, game consoles and portable media players, challenging the bulky LCDs that rely on backlighting. However, industry watchers say it will take years to see obvious winners if any emerging technology can replace the LCD screen.
OLED (organic light emitting diodes) and bistable technology are the most likely to challenge the LCD display technology. OLED display power consumption than the same size LCD screen 40% less. Since there is no need for backlighting, OLED display thickness is only half of the LCD screen.
These technologies have been used on some smaller portable devices such as Samsung Electronics and Reigncom's music player and Kyocera's mobile phone. Sony plans to sell small-size televisions with OLED displays later this year.
Research Institute LehmanBrothers analyst in South Korea JamesKim said that in the handheld device, the display is the largest power consumption. The first is the power, and then perhaps the brightness.
Analysts believe that the recent listing of the iPhone in the United States because of its use of LCD TV screen test product battery life is short, this phone may eventually use OLED display.
Prudential investment and securities company analyst KimWoon-ho said that for Apple, the transition to the OLED display is meaningful. They are working to improve the battery problem. OLED manufacturers are also looking forward to Apple to make such a change, although there is no definite plan.
This new display of advertising has caused Samsung Electronics and Sony LCD manufacturers such as the concern, because the price of liquid crystal display in the past year has dropped by one-third.
Samsung SDI already in production OLED display. Taiwan's Chi Mei Electronics is also at full capacity to produce this display.
According to market research firm iSuppli said, low-power OLED display and low-power LCD display market will grow rapidly. By 2012, the market's sales revenue will grow from $ 6 billion in 2007 to $ 24 billion, a compound annual growth rate of 27%.
Developing new technology is expensive. As a result, liquid crystal display manufacturers such as LG Philips LCD are using existing power control technologies and optical sensors for backlighting to improve existing LCD technology.
However, some industry experts believe that OLED technology will eventually be used for large-size TV. Chi Mei Electronics president PeterChen said, OLED display price is 1.7 to 1.8 times the LCD screen. Before the price dropped significantly, OLED display will not have greater competitiveness.
Competition with the OLED display is bistable display. This display still retains the image after a power outage and applies to the secondary display of the public display and the device, although there are still image quality problems in the bistable display.
Another product is a color flexible OLED display. LG Philips LCD recently introduced a 4-inch full-color flexible OLED display, but this size is still too small for handheld e-books.
This is just the beginning. One day, newspapers or magazines that can be updated by wireless or can be rolled up or folded, as easily as a piece of paper. Samsung Electronics Chief Technology Officer ChungHo-kyoon said that at that time, we will see the real difference between the display technology.
